container

The invention relates to a container with a conical cardboard trough, which on its inside with one of a Existing plastic film, deep-drawn into the cardboard trough Plastic trough is in contact, which is around the top of the cardboard trough as well as over extends a short distance down the outside of the cardboard tray.

Containers of this type are generally used for the packaging of margarine, jam, etc., with the containers are filled with the filling material at a different location than the one at which the containers are produced will. For this reason, the containers must be transported and stored, with both For reasons of space, they can be stacked one inside the other during transport and storage.

If the containers are to be separated from one another for the purpose of filling, i.e. they are to be singled out, this does not happen seldom do two or even more containers stick together. In the case of large stacking heights, it can also happen that the containers arranged at the very bottom of the floor are firmly wedged together and discarded Need to become.

Such containers have accordingly been provided with different types of support or stacking lips, with these lips have been provided on the inside or outside of the receptacles to wedge one another to prevent with or due to the stacking.

The above-mentioned stack lips are generally made of the plastic trough or the material of the plastic trough shaped, which is arranged in the cardboard trough, either at the top or at the bottom of the Container.

In the case of containers whose stacking lips are arranged on their upper section, the stacking lips can be removed from the Flange of the plastic tray are formed, which is bent over the upper edge of the cardboard tray, wherein the Extend lips around the opening of the container. and are in contact with the outside of the cardboard tray. In another embodiment, the stack lips are as Support lips formed which are pressed or shaped at the corners of the container in the plastic trough.

However, it has been shown that the known containers of the type described above have certain disadvantages. For example, the number of support lips formed in the plastic trough influences the internal volume of the container. For various reasons, the containers

BOEHMERT & BOEHMERT

generally be completely filled, so that when finished product, i.e. the filled container, there is no air inside. Shape and size of the outside of the container is also of great importance as there are provided on the outside of the container Provide support lips the required space, this size is of considerable importance because Such containers often have to be packed or stored and transported in very large numbers.

The present invention is based on the object of the known containers of the type described at the outset To improve the genus while avoiding its disadvantages.

According to the invention, the solution to this problem is to that the cardboard trough has recesses on the upper edge portion of its end faces, through which plastic material of the plastic trough is pressed to the outside beyond the cardboard trough, which is when stacked a plurality of containers forms a support surface for a further container arranged under the container.

Preferred embodiments of the present invention result from the subclaims.

The container according to the invention meets the requirements in a remarkable way, while at the same time remaining simple and cheap to manufacture is. Due to the fact that the front sides of the cardboard tray each have a front flap that is from The bottom is folded up, with the front flap on wall sections rests that are bent inward from the long walls of the cardboard tray, the result is astonishing high strength of the container according to the invention, and in particular in the area of the upper edge section

the end walls. However, this is absolutely necessary if you want to attach stacking lips in this area at all wants, because the flexibility or elasticity of a conventionally manufactured end wall is only so great is that there is formed stacking lips formed in the upper central portion of the end walls would not function as intended. One was therefore with previously known configurations forced to attach the stack lips to the corner portions of the container.

The invention is further explained below using an exemplary embodiment with reference to a drawing. It shows:

1 shows a perspective illustration of a container according to the invention;

FIG. 2 shows a central vertical section through a side wall of the container according to FIG Fig. 1;

3 shows a perspective illustration of the erected or folded from a blank Cardboard trough which is provided with cutouts according to the invention in both of its front sides; and

FIG. 4 shows a plan view of the blank for the cardboard trough according to FIG. 3.

A container 1 according to the invention, as shown in FIG. 1 consists of a conical trough 2 made of cardboard and a trough 3 made of a plastic film or a plastic film that is in contact with the inside of the cardboard tray 2. When manufacturing of the container 1, the cardboard trough 2 is arranged in a hollow shape, whereupon the cardboard trough 2 in turn for the thermoforming of a plastic film or a plastic sheet to a plastic trough 3 inside the cardboard

trough 2 serves as a form. During the deep-drawing of the plastic film into the cardboard trough 2, what with the help is caused by pressure and / or vacuum, the plastic ilm pressed into recesses or cutouts 4 which are present in the end faces 5 of the cardboard tray 2. These incisions or cutouts 4 are obtained by themselves when folding or erecting the walls of the cardboard tray 2. The plastic trough 3 has an integrally formed one Edge 6, which extends around the upper edge 8 (FIG. 3) of the cardboard tray 2. It also extends it is on the outside of the cardboard tray 2 over a short distance down and ends in a flange 7, which extends outward and downward. The edge portion 6 with its flange 7 are provided to with to cooperate with a cover, not shown in the drawing, etc. The cutouts 4 at the top 8 of the end faces 5 are obtained from plastic material, which comes from the trough 3 made of plastic film and has been pressed outwards accordingly, wherein stack lips 9 are formed which have a downwardly directed support surface 10 for a container 1, which in a stack consisting of a number of containers 1 under the relevant container 1 is arranged.

FIG. 2 shows a cross section through an end face 5 of the container 1 shown in FIG. 1. From FIG. 2 can be seen, inter alia, how the stacking lip 9 extends outward, and that its support surface 10 on a End flap 14 rests from the bottom 11 of the cardboard tray 2 is folded up, and finally that it runs out in the edge 6 or ends in this.

The blank shown in FIG. 4 shows the base and two opposing side walls 12

and 13 which _r can be folded upward and bent with their end portions inwardly toward each other to thereby form the side walls of the trough and part of its end walls. The end flaps 14 can also be folded upwards, specifically to the inwardly bent end sections of the side walls 12, 13, in order to bridge the ends of the side walls 12, 13. The end flaps 14 can be fastened to the side walls 12, 13, for example by means of an adhesive, in which case the cardboard trough 2 shown in FIG. 3 or ultimately the container 1 shown in FIG. 1 is created. The end flaps 14 have a height which is less than the height of the side walls 12, 13, so that it is not necessary to provide the cardboard blank with recesses or to cut it out in order to get to the cutouts 4. Because of this fact, a cardboard blank is obtained with a correspondingly reduced lengthwise extension in the longitudinal direction, which results in a considerable saving in material when punching the blanks. The finished container 1 possesses tapered walls, so that the containers 1 can be stacked.
